To all whom it may concern:

Be it known that I, JosEPH HEATON, .a subject of the King of GreatBritain, residing at Hampton Station, county of Kings, in the Provinceof New Brunswick, Canada, have invented certain new and usefulImprovements in Acetylene-Gas Generators; and I do hereby declare thatthe following is a full, clear, and exact descri tion of-the invention,such as wi ll enable ot ers skilled in the artto which it appertains tomake and use the same.

Myinvention relates to acetylene generators.

The object of my inventionis to provide a generator of few "movableparts andof simple I and construction.

A more specific ob ect is to provide a carbid feed which'is certaininits action and which will not clog. r A further objectis to provideaconstruction in which a movable gas dome is rendered unnecessary byutilizing the pressure of a column of water. i

A further object is to provide a simple re-' movable scrubbing device. Afurther object is to provide a pressure regulatingchamber attacheddirect to the.

generator.

A further object is to provide a'safety device adapted to cut off thecarbid feed in case of fire; and, my invention consistsof theconstruction, combination and arrangement of parts, as hereinillustrated, described and claimed.

In the accom anying drawings, formin part of this app ication, I haveillustrate one form of embodiment of my invention, in which drawingssimilar reference characters designate corresponding parts, and inwhich:

Figure 1 is a vertical central section thro h the generator and carbidreceptacle; i 2 is a vertical section through the head 0% a carbid feedcontrolling rod.

Referring to the drawin s, 1 'desi nates a tank, having adjacent itsower wa adecanting pipe 2, and the pipe has thereon a closure 3. Securedto the inner face of the vertical wall of the tank 1,'is a plurality ofstra s 4, in which is rockably disposed a vertica rod 5, having at itslowerend a horizontally disposed agitating arm 6, and having a handle 7on its upper end, by means of which the s ent carbid at the bottom ofthetank 1 mag e agitated. I

isposed' within the tank 1 is a gas dome 8,

having secured to its lower edge the lower ends of the stra s 9, theupper ends of which are securely b0 ted to the upper edge of the tank 1,so that the dome is rigidly held against movement. The dome 8 isprovided with a reduced u or end 10, having a,fiange 10, on which isisposed the carbid receptacle 11, having an opening 12 in its bottom. Asshown, the lower portion of the carbid chamber has an inclined bottom,which extends within the reduced portion 10 of the dome. The verticalwall of the carbid 'receptacle 11 is provided with a transparentsection13, by means of which the contents of the lower edge'of t e dome andfrom thence into the building, gas would not escape under the 'edgeofthe dome; but would escape through the safetyliipe 14.

Disposed in the ome 8 is an annular hollow float 15 carrying a spider-16, towhich is connected the rod17, rojecti throughv'the opening 12 ofthe car id chef flier.

Carried by the upper end of the rod 17, is a conical head 18, having aconcave annular recess 19 in its under surface, and having thenearly-vertical face 19 at the periphery of its base. The head isrovided with a shank 20, having the bevele lower face 21. The head 18projects into the bod of carbid B,

and its conical portion aifor s little resistance to its movementthrough said body. The vertical face 19 readil permits the carbid topass the head, and w en the head 18 is depressed by movement ofthe float15, the concave channel 19 does not retain any of the carbid between itand the inclined bottom of Y agement throu h a tube 24, whichis carriedby the carbitl chamber 11. A washer 25 is secured on the rod 23, and isadapted to contact with the upper end of the tube 24 to-limit thedownward movement of the rod 23. Secured to the up er end of the rod 23is a button 26, adapted to contact with the lever 27, which is pivotedat 28, and one end of which works in and is guided by a slot 29 formedin the wall of an interiorly screw-threaded collar 30, which forms partof the closure for the charging opening 30 in the upper wall of thecarbld receptacle 11. A tubular plug 31 is placed in screw-threaded enagement with the collar 30, and is providetl with teeth 32 on the loweredge of its wall. The teeth 32 are inclined, so that the plug' 31 ma bescrewed downward into-engagement wit the collar 30, and its teeth willride over the projecting end of the lever 27, but as long as there is abody of water A within the tank 1 at the height of the lower edge of thegas dome 8, the screw-threaded plug 31 can not be unscrewed because ofthe engagement of the lever 27 with the teeth 32.

. water is decanted, the float 22 will drop and 5 conduit must passthrough the fabric, wherewithdraw the rod 23, so that the lever 27 iswithdrawn from enga ement with the teeth,

and the plug 31 may e unscrewed, and the carbid receptacle recharged.The object of this is to make it necessary to decant the water andcleanthe apparatus before putting in a fresh charge of carbid. The plu 31 isprovided with a lug 33 on its outer en havmg an opening 34 thereinadapted to receive an insertible instrument, by means of which the plugma be screwed into engagement with the col ar 30. v

A gas discharge conduit 35 is placed in connectlon with the upper end ofthe as dome, andhas its outer end closed by t is screwthreaded plug '36,which carries an interiorly projecting bent arm 37, covered by a fabric38, so that any gas which passes through the by the gas is scrubbed. Aservice pipe 39 is connected to the screw-threaded plu 36, and hasthereon an ordinary form of va ve 40.

As the dome 8 is fixed, and the pressure of the gas therein increases inproportion to its formation, it is necessary to have some kind ofpressure re lator in order to secure the best results. uch regulatingdevice as shown at 41 is placed on the service pipe 39.

Ha thus fully described my invention, What I c aim as new'and desire tosecure by Letters Patent, is:
